Answer 1

To validate an email in PHP, use PHP's built in filters. See here for full details:

• http://www.php.net/manual/en/filter.examples.validation.php

Taken from the above URL, here's an example of how to validate an email:

if (filter_var($email_a, FILTER_VALIDATE_EMAIL)) {
  echo "This ($email_a) email address is considered valid.";
}

Applied to your code, this would make your valid_email() function the following:

function valid_email($address) 
  return filter_var($address, FILTER_VALIDATE_EMAIL);
}
